Abstract: The present invention relates to a new spongy material consisting essentially of hyaluronic acid or its derivatives. The characteristics of the new pharmaceutical preparations consist in assuring high concentrations of active principle for a long period of time, by exploiting the characteristics of slow release of the active principle. 
     The new pharmaceutical preparations can be utilized advantageously in all the numerous situations of microsurgical practice (in particular the ones relating to ear or in odontostomatology), in which it is necessary to use a substance that can be metabolized by the organism and is capable of making easier flap take, reepithelialization of mucous membranes, stabilization of grafts and filling of cavities. 
     The specific use of the new pharmaceutical preparations is particularly important and useful in the various ear pathologies and in the practice of otologic, otoneurosurgical and odontostomatological microsurgery, such as for instance repair of tympanic perforations.

Abstract: A microprocessor provides a bus state referred to as "loop-back". This state holds the data bus at valid logic levels, without use of resistors, after a read transaction has been completed and there are no pending bus transactions. When this state is entered, the data just read from the data bus (220) is driven back onto the data bus, and the device (210, 21N) which had provided the data is placed in the tri-state (high-impedance) condition. This loop-back feature, combined with the fact that all other outputs are held at their previous values, provides for near-zero power dissipation on the bus. The inventive technique avoids the use of pull-up resistors (R₁... R n ), which are provided on prior art tri-state busses (C₁ ... C n ) to ensure that the busses do not float and enter the threshold region where high power dissipation occurs.

Abstract: L'invention se rapporte à un appareil de coulage en continu d'une tôle mince, utilisant deux cylindres jumelés qui comprend: une buse (14) pour l'amenée du métal en fusion; une paire de cylindres de coulage (11, 12) qui assurent le coulage du métal en fusion amené par la buse (14) pour lui donner la forme d'une tôle mince et qui sont disposés en parallèle l'un par rapport à l'autre et à l'horizontale, ces cylindres étant en outre refroidis et mis en rotation opposée; ainsi qu'une bobineuse (17) et une feuille de support (16) s'étendant essentiellement à l'horizontale sous la paire des cylindres de coulage et enroulée par la bobineuse. Etant donné que la tôle mince coulée ne subit aucune force de tension, il est possible de couler en continu non seulement des matériaux ductiles mais également des matériaux fragiles, pour leur donner la forme d'une tôle mince. En outre, une tôle d'assise, nécessaire au moment où débute le coulage de la tôle mince, peut être produite et, même en cas de rupture de la tôle mince, le coulage en continu peut être poursuivi sans qu'il soit nécessaire d'arrêter l'appareil.

Abstract: 5 n7 An optical pickup head apparatus comprises a first coherent light source for emitting a coherent light serving as a main beam, and a second coherent light source for emitting a coherent light having a polarized plane at a right angle to the polarized plane of the coherent light emitted from the first coherent light source. When the coherent light emitted from the second coherent light source is incident upon a phase plate, the phase plate yields a sub-beam presenting a distribution of light intensity having peak values at at least both sides of the center of the sub-beam on a plane vertical with respect to the optical axis of the coherent light. Focusing means overlaps the main beam emitted from the first coherent light source on the sub-beam emitted from the phase plate, causing the resulting overlapped beam to be focused on the information-recorded surface of an optical disk. When a focused beam as reflected from the information-recorded surface of the optical disk is incident upon polarized beam separating means, the polarized beam separating means yields the transmitted beam as divided into the main beam and the sub-beam. Optical detecting means individually detects and supplies the light intensities of the main beam and the sub-beam emitted from the polarized beam separating means.

Abstract: MOSFETs and IGBTs contain parasitic structures (bipolar transistors or thyristors) which can be switched on, for example when short-circuiting the load. The component can be destroyed by this. Switching on of the parasitic structures is substantially suppressed in that the heavily doped contact zone (6) producing a local short circuit between the emitter zone (7) and the base zone (6) has a lateral separation of between 0 and 1  mu m from the gate electrode. The lateral voltage drop below the emitter (7) (source) is thereby kept very low, and the voltage across the pn junction between the emitter and the contact zone remains less than approximately 0.5 V. <IMAGE>
